METAL-SAHEARING DEVICE.

SPECIFICATION forming part of Letters Patent No. 742,942, dated November 3, 1903. Application filed June 30,1903- Serial No. 163,800. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WIEK, a citizen of the United States, residing at Iola, in the metal, or both, may be acted upon at asingle operation, andone in which a direct pressure upon the movable shearing-blade will be had during the operation of the device.

To these ends the invention comprises the novel details of construction and combination ofjparts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of a metal-shearing device embodying my invention. Fig. 2 is a vertical transverse section on the line 2 2 of Fig. 1.

Referring to the drawings, 1 indicates the base,of any suitable construction or material, to which the frame of the machine is attached by bolts or otherwise. The frame of the machine consists of a table or support 2, from the rear end of which arises an integral head or standard 3, to which latter is bolted or otherwise secured a horizontal arm 4, which overhangs and is coincidentvin length with the table 2.

5 indicates a fixed shearing knife or blade carried by and projecting slightly above the table or support 2, and 6 a cooperating movable knife or blade eccentrically pivoted at its rear upper corner to the arm 4, as at 7, and provided at its forward end with a semicircular recess 8, which receives the circular head 9 of a lever 10, eccentrically pivoted, as at 11, to the forward end of arm 4: and adapted when raised and lowered to swing upon its pivot 11 and, owing to its eccentricity, act upon the blade 6 for raising or lowering the latter. In this connection it is to be noted that owingto the eccentrically-pivoted head of the lever being in direct engagement with the movable blade in advance of the pivotal point of the latter and above its cutting edge force or pressure applied to the lever during the operation of the device will be transmitted directly to the blade, thus materially increasing the cutting strength of the latter. It is also to be noted that the inner face of the blade 6 contacts with the outer face of blade 5 and that when the forward end of the former is elevated its cutting edges 12 and 13 will be disposed at an angle relative to their normal positions, whereby during the depression of the blade they will act with a shearingcut upon the material operated upon, and, further, that owing to the blade being eccentrically pivoted its movement will be such as to compensate for the head in its movements, thus obviating liability of the head moving out of or binding in the recess.

14 designates a series of perforations formed transversely through the arm at beneath and slightly in rear of the pivotal point 7 of the blade 6. These perforations vary in size and are designed for the reception of bar or rod metal, which will be cut or sheared by the,

edge 12 of blade 6 during the operation of the latter.

From the foregoing it will be seen that I produce a device of simple construction which will be efficient in operation and one which is admirably adapted for the attainment of the ends in view. It is, however,.to be understood that I do not limit myself to the precise details herein shown and described, in-

asmuch as minor changes may be made there-' in without departing from the spirit or scope of the invention.

Having thus described my invention, what I claim is 1. In a device of the class described, the

combination with a table or support, of a blade carried thereby, an overhanging arm sustained above the table, a movable blade pivoted adjacent to its rear end to the arm and provided at its forward end with a semicircular recess, and an operating-lever having a circular head eccentrically pivoted to forations in the latter, and provided at its] my own I have hereto affixed my signature forward end with a semicircular recess, and in the presence of two witnesses. an operating-lever having a circular head eccentrically pivoted to the arm and in direct WILLIAM WEEK 5 engagement with the semicircular recess of Witnesses:

the blade. CHRIS BITTER,

In testimony that I claim the foregoing as HATTIE BITTER.
